The swirls created by milk poured into coffee or the shudders that can jolt airplanes in flight are examples of turbulence, the chaotic movement of matter found throughout nature. Turbulence also occurs within tokamaks, doughnut-shaped facilities that house the plasma that fuels fusion reactions. Now, scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have discovered that turbulence may play an increased role in affecting the self-driven, or bootstrap, current in plasma that is necessary for tokamak fusion reactions.

Turbulence, the swirling eddies and currents that jostle fluids and air, is traditionally seen as disruptive of efforts to capture and control on Earth the fusion energy that powers the sun and stars. Now a discovery by scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and General Atomics has found that enhanced turbulence in the edge of the plasma may actually improve the thermal insulation required to achieve fusion energy.

When friends asked Promise Adebayo-Ige what he was doing over the summer, he told them he was trying to save the world by working at a national laboratory devoted to developing fusion energy.
Adebayo-Ige has been fascinated with the idea of fusion as an inexhaustible, inexpensive, and clean source of generating electric energy since he was a teenager. Now a rising senior majoring in chemical engineering at the University of Pennsylvania, he plans to attend graduate school in nuclear engineering with the goal of working on the quest for fusion energy

Promise Adebayo-Ige, a chemical engineering major at the University of Pennsylvania, has been fascinated by fusion energy since he was in high school. He came to the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory for a chance to do research in the field and spent his spare time training for his school’s soccer team and studying for graduate school entrance exams.

Low-temperature plasma, a rapidly expanding source of innovation in fields ranging from electronics to health care to space exploration, is a highly complex state of matter. So complex that the Princeton Plasma Physics Laboratory (PPPL) has teamed with Princeton University to become home to a collaborative facility open to researchers from across the country to advance the understanding and control of this dynamic physical state.
